Once limited to mission-critical devices, backup power solutions are now in demand for a wide range of electronics applications in industrial, commercial, and consumer end-products. While there are several options, the supercapacitor offers the most compact and energy-dense solution as an energy reservoir when the main supply is interrupted.
Diodes allow either the primary power source or the supercapacitor to power the system (Figure 5). Figure 5: Using a single supercapacitor in a power backup circuit eliminates the need for cell balancing but requires a step-up regulator to boost the supercapacitor’s output voltage.
Moreover, supercapacitors have much lower effective series resistance (ESR) than batteries. This allows them to provide power more efficiently without any danger of overheating. Supercapacitor power conversion efficacy of greater than 98% is typical.
Supercapacitors can operate between 0 volts and their maximum rated capacity. While efficient utilization of the supercapacitor’s available energy and power storage is achieved when operating over the widest voltage range, most electronic components have a minimum voltage threshold.
